【摘要】 采用几何方法设计实际非线性系统首先必须解决变换复杂、运算量大等问题,因此简化设计过程极为重要。本文基于变换思想得到两种方法并用于设计美国F-8 Crusader战斗机的纵向控制系统。仿真结果表明新的控制律明显优于原先的非线性最优控制律,且可保证飞机作大攻角飞行。更多还原

【Abstract】 To design actual nonlinear systems through geometric approach, at first we need sweep away the obstacle such as complex transformation and great amount of calculations. Therefore it is important to make the design procedure simple and clear. In this paper we have obtained two methods based upon transformation idea’s and applied them in designing the vertical control system of F-8 Crusader Fighter. The smiulation results show the new control law wofks much better than former noplinear optiumal control law and makes high-angle-attack flight available.更多还原
